APPARATUS and in Germany July 26, -11 Claims. (Cl. 198-'-35) Filled boxes or the like must frequently be subjected to further treatment, that is provided with a sealing strip or the like. In these circumstances it is important that once the boxes or the like are filled they should not be subjected to any further serious jolting likely to in- 7 MI over a table 2 inclined towards the deliveryposition of the articles. and is returned over, guide. rollers 3, 4; 5. The guide roller 4 is driven by means of a belt or a chain 6', I

The pile of articles on the side 1 of. the to": pile belt is driven forward in the direction jure the contents of the boxes. It is well known, for instance, that in the case of boxes filled with cigarettes, jolting or the like damages the ends of the'cigarettes and causes the tobacco at the ends to crumble. away.

The object of this invention is to convey the ready-filled and stacked boxes to the position where they are further treated so that for practical purposes they are sufficiently free from concussion, taking into consideration the fact that the boxes must arrive at such position lying flat on an horizontal table, while on the other hand it is impossible to insert the filled boxes in special magazines or the like owing to the shak ing it involves.

The articles are therefore simply deposited on a horizontal or approximately horizontal pi1e" table on which they are arranged erect and in serial order. This pile is moved forward and, each time, the foremost article of the pile .is displaced in a vertical direction by a member which engages with it irictionallyso that there is an instant increase in the forwarding speed in such manner that a catch or the like can perform the further delivery in a manner sufficiently free from concussion for practicalpurposes; this being done along a curved path so that the box is transferred from the vertical position to afiat posi-' tion and arrives in this position on the feed table where, by means of further catches orthe like,

it is carried to the position where it is subjected to further treatment.

The apparatus for carrying out the process is preferably constructed in such manner that the pile of boxes is transferred to a conveyer belt which carries away the foremost box by friction and passes it to an adjacent curved guideway; a gripping member fixed to an endless chain or thelike, which moves at the'same or at a somewhat greater speed than the delivery speed of the belt, seizes the box totally or partially transferred to the curved guideway, and while moving parallel to the guideway delivers the article to the horizontal reception table.

The annexed drawing shows a vertical longitudinal section of one form of construction of the apparatus.

The filled boxes :1 are deposited erect on the upper surface -1 of an endless belt, which runs of the arrow towards the side 7 ofan endless belt passing over the guide 'rollersii' and 9. The surface 7 of this-endless belt is so arranged that it runs pa'rallel or approximatelyparallel to the end wall of theiront box facing it. By-means of gearing 10, 11a guide roller 9 is driven so as to impart a downward movement to the working surface of the endless belt. \The gear wheel 10 engages with a driving wheel 12 mounted on the axle of a sprocket wheel 13. Overthis sprocket wheel there passes-a chain 14. which also runs over a second .sprocket wheel 3.5}8I1d causes a transfer-of the articles toia guide chan+ nel 16" which is arcuate, so that it transfers the boxes delivered to it from the original verticalor approximately vertical position to the horizontal position and thendeliversthem flat to designed that first the foremost'box of the pile is carried away by friction by the working sur'- face '7 of the conveyer belt and drawn downwards from the pile. In this operation there .is practically: no shock. The box then acquires the acceleration of the conveyer belt and is engaged by the respective catch 18 of the chain 14 before the action of the surface '7' on the box has finished The box has, however, already partially entered into the guide channel 16, so that the catch can pass the box through the guide channel practically without shock.- I

The chain is driven by the belt 19, of which the pulley 20 is fixed to the axleof the sprocket wheel 15. This axle actuates the drivingwheel 23 for the chainfi, through the gearing 21, 22.

In the form of construction illustrated. the boxes deposited on the table 1'7 by the respective catches 18. 'are thrust forward still further and; then transferred to a catch 24 which is fixed to an endless chain 25. This chain is passed over a sprocket wheel 26 in such manner that the working surface of the chain runs parallel to the surface of the table 17, that is to say horizontally. At the moment when the catch box it is engaged by new catches its 24 and passed on to the table 17 to the position where it is subjected to further treatment.

In order that the second article in the pile should not fall over while the 1251 article is being removed by thesurface It! the colfifille! belt, a brush roller 2'7 is provided which is mounted on theend of a swinging arm 28, which in its turn pivots about the axis of the sprocket wheel 13.
